HOUSTON – A U.S. Customs and Border Protection computer outage was affecting operations at IAH Bush airport and nationwide Monday night, officials said.

The incident was reported about 5 p.m.

A Houston airport system official Bill Bengly said Houston's airport has been cleared about 9 p.m. after the outage.

CBP said they used alternative measures at airports that experienced the sudden outage. International travelers experienced longer wait times than usual, CBP offcials said.

The U.S. Customs and Border Protection issued a statement:

"U.S. Customs and Border Protection is experiencing a temporary outage with its processing systems at various air ports of entry and taking immediate action to address the technology disruption.  CBP officers continue to process international travelers using alternative procedures until systems are back online. Travelers at some ports of entry are experiencing longer than usual wait times and CBP officers are working to process travelers as quickly as possible while maintaining the highest levels of security."

CBP said they monitor their system and computer information through diagnostics to fix the main problem that caused the outage.
